What is the output of:

class Base {
  static #field = 'hello';

  static get() {
    return this.#field;
  }
}

class Sub extends Base {}

// This one isn't controversial
Base.get() // => 'hello'

// But what does this do?
Sub.get()

I want it to equal 'hello', but I can't find where the behavior is defined. It's likely just because I'm not familiar enough with the spec text.

Maybe it's an error, though? Since I don't think Sub has #field in its [[PrivateFieldValues]] list, unless there's some super class iteration I'm not seeing.
